The Bitcoin Operations Technology Group (Optech) works to bring the best open source technologies and techniques to Bitcoin-using businesses in order to lower costs and improve customer experiences. An initial focus for the group is working with its member organizations to reduce transaction sizes and minimize the effect of subsequent transaction fee increases. We provide workshops, documentation, weekly newsletters, original research, case studies and announcements, and help facilitate improved relations between businesses and the open source community.
